An investigation of the relationship between National Institutes of Health (NIH) funding and the quantity and nature of biomedical publications is reported for 120 U.S. medical school complexes. A correlation of 0.95 was found between the amount of NIH funds received and the number of biomedical publications from the medical schools. Medical school ranks based on bibliometric measures were found to correlate at the 0.80-0.90 level with ranks based on peer assessments of the schools. The characteristics of the medical school papers varied with the type of school. The average citation influence per paper increased with the publication size of the schools. This was true even when factors such as public versus private control, geographic region, average research level (from basic to clinical), and subject emphasis were controlled. The positive relationship between number of papers from a school and its citation influence holds within individual research levels and within subfields. 相似文献

A self-consistent methodology is developed for determining citation based influence measures for scientific journals, subfields and fields. Starting with the cross citing matrix between journals or between aggregates of journals, an eigenvalue problem is formulated leading to a size independent influence weight for each journal or aggregate. Two other measures, the influence per publication and the total influence are then defined. Hierarchical influence diagrams and numerical data are presented to display journal interrelationships for journals within the subfields of physics. A wide range in influence is found between the most influential and least influential or peripheral journals. 相似文献

The aim of this study was to investigate the effect of immersive three-dimensional (3D) interactive virtual reality (VR) on anatomy training in undergraduate physical therapy students. A total of 72 students were included in the study. The students were randomized into control (n = 36) and VR (n = 36) group according to the Kolb Learning Style Inventory, sex, and Purdue Spatial Visualization Test Rotations (PSVT-R). Each student completed a pre-intervention and post-intervention test, consisting of 15 multiple-choice questions. There was no significant difference between the two groups in terms of age, sex, Kolb Learning Style Inventory distribution, and the PSVT-R (P > 0.05). The post-test scores were significantly higher compared to pre-test scores in both the VR group (P < 0.001) and the control group (P < 0.001). The difference between the pre-test and post-test results was found to be significantly higher in favor of the VR group (P < 0.001). In this study, anatomy training with a 3D immersive VR system was found to be beneficial. These results suggest that VR systems can be used as an alternative method to the conventional anatomy training approach for health students. 相似文献

Due to the fact that mediated associations are a central aspect of many mass communication theories, their measurement is of central interest for communication research. Mediated associations are defined as the repeated pairing of an object (e.g., social group, political party) with specific attributes (e.g., crime, economy). In this article, we introduce a recently developed, automated text-analytic technique. We present an application of this method in the media stereotyping domain via the content analysis of German news coverage of Islam. As predicted, the analysis revealed substantial mediated associations between Islam-related concepts and violence (e.g., “Koran + violence”), terror (e.g., “Islam + terror”), dehumanization (e.g., “Muslims + animal-related terms”), and general negativity (valence). We discuss the promises and pitfalls of this method, make software suggestions, and provide application-related information for speedy dissemination in communication research. 相似文献
